Question

1. A sample of Oxygen gas occupies a volume of 250 ml at 0.97 atm pressure. What volume will it occupy at 1.05 atm pressure?

Answer 1

The volume will be 0,23 L

Step-by-step explanation:

We use Boyle Mariotte's law: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally. We convert the unit of volume in ml into L: 250/1000= 0,250 L

P1xV1=P2xV2

V2= (P1xV1)/V2=(0,97 atm x 0,250 L)/1,05 atm =0,23 L
